Dallas Cowboys quarterback Tony Romo did not practice Wednesday as he followed his normal schedule and continued to get treatment for his injured back in preparation for Sunday's game against the Jacksonville Jaguars in London.

Romo, who has not practiced on a Wednesday since Week 2, remained at the team hotel. He then took part in the walk-through at the team's hotel.

Coach Jason Garrett is hopeful that Romo will be able to practice Thursday.

"Following the normal schedule but also listening to his body," Garrett said before Wednesday's practice at Saracens Rugby Club's Allianz Park. "We had a good, productive walk-through at the hotel today and we anticipate him adopting that schedule that we've had for most of the year."

Romo took part in the light walk-through Tuesday after the Cowboys arrived in London and there were more encouraging signs that he was able to take part in Wednesday's walk-through.

Garrett said the decision to start Romo on Sunday will be a medical one with input from Romo.

"When you're talking about the player's ability to function and how he feels it's always (a gray area), so honest feedback is important," Garrett said. "Honest evaluation is important, what we see, how he feels, and what we do, those things are a constant discussion. That's not only with Tony; that's with everybody on our football team. We have to make the best decisions during the week to get him ready to play on Sunday to make the best decision on Sunday."

Romo, who has 15 touchdowns and six interceptions this season, suffered two transverse process fractures in his back after he was sacked in the Cowboys' 20-17 overtime loss to the Washington Redskins in Week 8. He did not play in last Sunday's 28-17 defeat to the Arizona Cardinals.

"It's progressing," Romo said Tuesday. "Each day it gets a little bit of improvement, and I think that you just keep trying to figure out what you're able to do each day and then you go on to the next day. We'll figure out if we're able to improve enough to be ready to go."
